Answer:
And we can solve for x in order to find the number hours using to decorate the house.
We can subtract in both sides 115 and we got:
And now we can divide both sides by 5 and we got:
So then the number of hours spent to decorate the house are 25
Step-by-step explanation:
Based on the information given we can model this function with this formula:
Where y represent the total cost paid, m the cost per hour representing the slope and x the number of hours worked and finally b the initial cost for the materials. Then our function is given by:
And we can solve for x in order to find the number hours using to decorate the house.
We can subtract in both sides 115 and we got:
And now we can divide both sides by 5 and we got:
So then the number of hours spent to decorate the house are 25
Answer:
undefined
Step-by-step explanation:
x=-6 is a vertical line at x=-6.
Any vertical line has an undefined slope.
Let's pick two points on x=-6– (-6,1) and (-6,0)
(1-0)/(-6-(-6))=1/-6+6=1/0
Because you cannot divide by 0, a vetical line has an undefined slope.
Answer: C. p=6 x 2w
Step-by-step explanation:
One lap. Usually, it would take 4 laps to walk a mile, but since its 1/4 it equals One lap.
It takes 40 minutes more going up or 40/60 = 0.67 hours
more.
Let us say that:
t = the time required for him running down
t + 0.67 = time required for him running up
Since the distance of running up and down must be equal
therefore:
(3 miles / hr) * (t + 0.67) = (5 miles / h) * t
3 t + 2.01 = 5 t
2 t = 2.01
t = 1.005 hr
So the total length of the hike is:
length = 2 * (5 miles / hr) * (1.005 hr)
<span>length = 10.05 miles</span>
